A Time-Dependent
Deteriorating EOQ Model with Selling Price and Stock-Dependent
Demand During Inflation Under Supplier Credits
--Ravi Gor and Nita Shah
In
this paper, an inventory model is developed for deteriorating
items for which the demand is dependent on the selling price
as well as stock. The units in the inventory are subject to
a constant rate of deterioration. Shortages are not allowed
and the supplier provides a cash discount and a few permissible
delays in payments. An optimal solution is characterized to
optimize the net profit. An easy-to-use algorithm is given
to find the optimal selling price, the optimal order quantity
and a replenishment cycle time that maximizes the net profit.
A numerical example is given to illustrate theoretical results
and a sensitivity analysis of parameters on the optimal solutions
is carried out at the end.

Evaluation
and Economic Selection of Raw Materials' Inventory Control
Policies: A Case Study
--Mahendra
Pratap and Harwinder Singh
In
this modern and competitive world, one of the major problems
of every company is that of cost control and reduction. Inventory
management is used as a scientific device for controlling
inventory cost and eliminating waste and is regarded as an
integral part of industrial management. While other methods
of cost control have to encounter resistance or reluctance
of workers, inventory management can secure rich dividends
much easily and without inviting any resistance. In the present
study, inventory data of raw materials has been collected
and a stochastic analytical inventory model has been proposed
for economic selection of inventory control factors and elimination
of shortages of raw materials. As determined by this proposed
model, the total inventory cost has been less than the existing
inventory cost. The result of the study shows that companies
can save considerable amount of money per annum by adopting
this model.

Scheduling
with Processing Alternatives: An Approach to Minimize Makespan
in a Multi-Product Manufacturing Industry
--V Mahesh, Sandeep Dulluri, A Chennakesava
Reddy and C S P Rao
Traditionally,
process planning and shop floor scheduling are viewed as separate
and discrete manufacturing activities. Conflict arises between
these two activities, as process planning is a technique-based,
cost or quality-driven activity and scheduling is a mathematical
due-date driven activity. This paper describes an approach
in which process planning and shop floor scheduling are integrated
in order to achieve a unified manufacturing aim. The integration
of process planning and scheduling makes way for the effective
use of production resources and creation of realistic process
plans that can be readily executed with less modifications
in a computer integrated manufacturing system. In this paper
the problems behind planning and scheduling in complex process
environments are analyzed and proposed to enhance the traditional
schedulers by planning capabilities to solve these problems.

Implementation
of Total Productive Manufacturing Concept with reference to
Lean Manufacturing in a Processing Industry in Mysore: A Practical
Approach
--V
Ramesh, K V Sreenivasa Prasad and T R Srinivas
This
study was done in a medium scale industry that manufactures
tyres in Mysore. It has been observed that, the breakdown
of some of the mills has been critical. Hence, it was decided
to apply Total Productive Maintenance (TPM) concept to this
industry. In this paper, we have collected the data of the
breakdowns of a 4 roll calendar mill, a 4 roll calendar warm-up
mill and a warm-up mill overhead conveyor and have discussed
the remedial measures for reducing the breakdowns of the 4
roll calendar mill. Lean manufacturing tools like Cause and
Effect diagram, Why-Why analysis and Kaizen techniques are
applied for the analysis.
